OF GENESEO, ASSIGNOR OF ONE-HALF HIS RIGHT TO E. E. SILL, OF BUFFALO,NEW YORK.

IMPROVEMENT IN HOSE-COUPLINGS.

Specification forming part of Letters Patent No. l 74,988, dated March21, 1876; application led August 14, 1875.

To all 'whom 'it may concern Be it known that I, AARON J. TYLER,ofGeneseo, in the county of Livingston and in the State of New York, haveinvented certain new and useful Improvements in Hose-Ocuplings; and dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,andto the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in 'the construction and arrangementot' a hose-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, l will now proceed to describe itsconstruction and operation, referrin g to the annexed drawing, in which-Figure 1 is a longitudinal section, and Fig. 2 a front viev, of mycoupling, showing its application to a curved spout. Fig. 3 is a sideView; and Fig. 4, a longitudinal section,

showing the application of my invention to.

straight spouts, or for coupling two pieces of hose together. 4

A represents' the curved spout of a pump, to which it is desired tocouple a hose, B. The coupling is composed of a flanged tube, C,provided with exterior circuinferential teeth or bent offsets a a, whichis inserted in-the hose B, and the hose then clamped by means of twosemi-tubular pieces, D D, whichhave grooves b b aroundrtheir innercircumference,

and provided with projecting ears or flangesV E E at their ends.4 Theseears or anges' are then fastened together b v bolts or screws d d,thereby firmly .clamping the hose on the interior tube G. From the-center of each clamp D extends an arm, G, upward for a suitabledistance, and between the upper ends of the two arms is pivoted a lever,H, the pivot'end of which is formed with a cam, e. On the outer side ofthe spout A is formed a lug or projectiomf, as shown in Fig. l.

When the hose is to be coupled to the spout it is irstclamped, as abovedescribed, the

clamps extending a suitable distance beyond the outer anged end of thetube C. Apacking-ring, h, is then placed on the flanged end of saidtube, and the coupling placed on the end ofthe spout, when, by throwingthe lever H inward over the top part of the spout, the cam e willoperate against the projection f and rmly draw the parts together,making a water-tight joint.

To uncouple the hose it is only necessary to throw the lever H outwardagain, when the hose will be free.

lt' the hose should break, the clamps can easily be removed, the hosecutoff, and the tlanged tube O inserted again, and the hose then clampedthereon, as before.

When the hose is to be coupled to a straight spout, as shown in Figs. 3and 4, the same iianged tube and clamps are used, but the arms G aremade short and provided on their ends with inwardly-projeciing inclinedflanges z' i, and the spout is provided with screw-flanges m m, for theflanges to ride on, and thus screw the parts together.

This form of my invention may be used for uniting or coupling two piecesot' hose together by having the screw-llanges m on one clamp, and thearms with inclined .il-anges on 'the oth er.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the interior ilanged and toothed tube G, the groovedclamps D, provided with ears E and fastened by bolts or screws d, thearms G G, projecting from the clamps, lever H, with cam e, and spout A,with projection j', all substantially as and for the purposes herein setfrth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 5th day of August, 1875.
